Aardvark: Tubulidentata

The deciding factor for where aardvarks live is availability of food. They also require sandy soil, as opposed to rocks, so that they can dig for termites. Aardvarks live in underground burrows that are 6.5 to 9.8 feet (2 to 3 meters) long, at 45 degree angles. At the end of the tunnel is a rounded "room" where the aardvark curls up to sleep. Female aardvarks give birth in this chamber. Although burrows usually have just one entrance, some have numerous entryways as well as several tunnels extending from the main passage.
